我是SQL Server的新手，我正在处理一个视图，该视图是从2个select语句的联合创建的，这些语句在视图中创建列并使用内部联接，左外部联接等。见下面的脚本。
我添加了
行(SUM(PR.amount) OVER (PARTITION BY YEAR(PR.posting_date), PR.lease_id, E.expense_id)) as Annual
创建一个列，显示每月个人费用的年度总和。不幸的是，因为SUM行在联合的两个部分中，我没有得到期望的结果。当posting_date，lease_id和expense id相同时，年度列中的总和应该相同。但是，即使所有这些参数都匹配，联盟的一半中的项目与联盟另一半的项目的总和也不同。
基本上我需要做的（我认为）是在union完成之后创建年度列，以便sum函数在进行计算时看到union的两个部分中的所有项。我正在考虑将整个事物嵌套在SELECT并将SUM线移出联盟的两个部分，但我不知道这是否有效或是否正确。
提前感谢您的建议。

您可以通过在视图中重构查询来解决此问题：
select t.*
from (<subquery1>
union
<subquery2>
) t
然后你可以这样做：
select t.*,
SUM(amount) OVER (PARTITION BY YEAR(posting_date), lease_id, expense_id)) as Annual
from (<subquery1>
union
<subquery2>
) t
您可能必须确保子查询返回所有字段 - amount，posting_date，lease_id和expense_id。
